Abstract

Methods and apparatus for processing title data watermarked with a code. At least a portion of the title data may be watermarked at a plurality of locations within the title data with customer information data, so that the title data provided to a customer includes the watermark information. To obtain the code from the watermarked title data, watermarking information associated with the watermarked title data is first received. The watermarking information identifies a plurality of locations and a number to frequency modulation relationship at each of the locations. A different modulation scheme may be used at each location. The watermarked title data is demodulated at each of the plurality of placement locations based on the number to frequency modulation relationship. The code is then generated from the demodulated watermarked title data. A verification indication is output based in part on the generated code.

Claims

1. A device, comprising:

a computer-readable medium configured to store watermarked title data, the title data being watermarked with a code; and

a processor, configured to extract the code from the watermarked title data on the computer-readable medium, by

receiving watermarking information associated with the watermarked title data, the watermarking information identifying a plurality of placement locations and a number to frequency modulation relationship at each of the plurality of placement locations;

demodulating the watermarked title data at each of the plurality of placement locations based on the number to frequency modulation relationship; and

generating the code from the demodulated watermarked title data.

4. The device of claim 1, wherein the code comprises a customer identification code, and the processor is further adapted to verify that the user of the watermarked title data is a customer authorized to use title data.

5. The device of claim 1, wherein the code comprises an identification code, and the processor is further adapted to determine whether the watermarked title data is an unauthorized copy of the title data based on the code.

6. The device of claim 1, wherein the computer-readable medium is adapted to store watermarked title data comprising a full-length movie title data, audio title data or software title data.

7. A method of processing title data watermarked with a code, comprising:

receiving watermarking information associated with the watermarked title data, the watermarking information identifying a plurality of placement locations and a number to frequency modulation relationship at each of the plurality of placement locations;

demodulating the watermarked title data at each of the plurality of placement locations based on the number to frequency modulation relationship;

generating the code from the demodulated watermarked title data; and

outputting a verification indication based in part on the generated code.

2. The device of claim 11, wherein the watermarking information comprises a correlation map and a watermarking key.

3. The device of claim 11, wherein the computer-readable medium comprises a CD or DVD, and the device further comprises a reading device.

8. The method of claim 7, wherein the method further comprises

communicating with a central database over a network to verify the generated code.

9. The method of claim 7, wherein the watermarking information comprises a correlation map and a watermarking key.

10. The method of claim 7, further comprising reading the watermarked title data from a CD or DVD.

11. The method of claim 7, wherein the code comprises a customer identification code, and the method further comprises verifying that the user of the watermarked title data is a customer authorized to use title data.

12. The method of claim 7, wherein the code comprises an identification code, and the method further comprises determining whether the watermarked title data is an unauthorized copy of the title data.

13. The method of claim 7, wherein the watermarked title data comprises a full-length movie title data, audio title data or software title data.

14. A computer-storage medium comprising title data that is watermarked with an identification code, the title data having at a plurality of locations the identification code modulated on the title data, with a different modulation scheme at each of the plurality of locations creating a random relationship between the identification code and modulation at each of the plurality of locations, and each of the plurality of locations being a random location within a group of available placement locations at which the title data has properties meeting at least one criterion.

15. The computer-storage medium of claim 14, wherein the title data is audio data and the modulation schemes used to modulate the title data alter the title data by a sufficiently small amount that the modulated data is not perceptible to a human listener of the audio title data.

16. The computer-storage medium of claim 14, wherein the computer-storage medium comprises a physical medium.

17. The computer-storage medium of claim 16, wherein the computer-storage medium comprises a computer disk.

18. The computer-storage medium of claim 14, wherein the computer-storage medium comprises data transmitted over a network.

19. The computer-storage medium of claim 16, wherein the plurality of locations have random positions on the computer-storage medium.

20. The computer-storage medium of claim 16, wherein the different modulation schemes are random.
